Product Description:

The MHD115B-035-NG0-BA is a servo motor developed by Bosch Rexroth Indramat for the MHD Synchronous Motors series. Within the type code, the 115 frame size and B length create a compact yet powerful form factor, while winding code 035 identifies its electrical profile. Deployed in industrial automation, the unit converts drive commands into precisely controlled torque and position for gantries, packaging lines, and material-handling stations. Because it operates as a permanent-magnet synchronous actuator, it maintains tight speed regulation when paired with compatible digital drives.

At standstill, the motor delivers a continuous torque of 50.0 Nm, allowing it to hold heavy loads without additional gearing. The centering shoulder measures 180 mm, and together with an output connector on side B, it supports straightforward machine integration. A smooth shaft with a factory-installed seal protects the internal bearings, and the housing has an IP65 rating that resists dust and low-pressure water jets. Normal operation is permitted between 0 to 40 °C, and heat is removed by natural convection, so no external blower is required. The insulation system meets Class F limits, and the motor can be mounted up to 1000 m above mean sea level without derating.

The feedback system relies on Digital servo feedback (HSF) that captures rotor position optically, enabling closed-loop control with a system accuracy of ± 0.5 angular minutes. Because the position transducer is relative, a homing routine is required after power-up. A flange diameter of 192 mm matches standard IEC mounting faces and simplifies mechanical integration. For applications that depend on drive-controlled stopping, the motor is supplied without a holding brake. During shutdown, it can be stored between -20 °C and +80 °C, and its electrical insulation maintains integrity across that range.
